Embodiment
The detailed features and advantage of the narration present invention in detail in a specific embodiment below, its content is enough to make any
Skilled in the art realises that the technology contents of the present invention and implement according to this, and specification according to disclosed by this specification, weigh
Profit is required and accompanying drawing, skilled person readily understands that the present invention related purpose and advantage.
Fig. 1 shows the general principle figure of accident indicator according to an embodiment of the invention.The accident indicator bag
Include central control unit 101, field programmable gate array (FPGA) module 103, the first relay 105, the first breaker 107,
Second relay 109, the second breaker 111.Central control unit 101 is responsible for system control, realizes detection and control logic
Operation is handled.Central control unit 101 is by failure that the dividing anomaly detected is two grades.Level fault is attached most importance to die
Barrier, directly affect equipment safety, cause system can not normal work, or system still run but be unsatisfactory for whole security functions will
Ask；Secondary failure is minor failure, and equipment safety is influenceed indirectly, and system is still normally run, and only non-safety function is caused necessarily
Influence.
FPGA module 103 is responsible for control and performed, and receives the process instruction from central control unit 101, completes digital quantity
Input and output.When central control unit 101 detects the level fault of correlation, the output of FPGA module 103 first output letter
Number (OUT1), wherein, first output signal is high level；When central control unit 101 detects the secondary failure of correlation,
FPGA module 103 exports the second output signal (OUT2), wherein, second output signal is high level.
What breaker was utilized is breaker overcurrent protection ejection principle.Equipment is normally, it is necessary to which breaker is placed in before
Closure state.When system detectio is to dependent failure, FPGA output OUT1, OUT2 be separately or concurrently placed in high level, at this moment after
Electrical equipment is acted, the closing of contact, resistance and breaker electrifying.At this moment, breaker series circuit operating current is more than the volume of breaker
Determine electric current, eject breaker, instruction system has failure.In the case of whole system is closed, breaker can also keep current
Fault indicating condition.That is, thread off and do not cut off the electricity supply after indicating, equipment startup optimization is not impacted.Release after failure, manually
Breaker is placed in closure state.
In one embodiment, the first breaker 107 and first resistor (R1) 106 are connected.First output signal (OUT1)
Coupled with the first relay 105, the first relay 105 and the first breaker 107 and the series circuit coupling of first resistor (R1) 106
Connect.Second breaker 109 and second resistance (R2) 110 are connected.Second output signal (OUT 2) is coupled with the second relay 111,
Second relay 111 and the second breaker 110 and the series circuit of second resistance (R2) 110 are coupled.
In one embodiment, power taking resistance R1, R2 resistance are 470 Ω, and first, second breaker internal resistance of selection is
376 Ω, the rated current of first, second breaker is 0.05A.Therefore it is electric in loop under normal working voltage 77V~137V
Flow for 0.09A~0.16A, according to the operation curve of breaker, (such as Fig. 2, wherein transverse axis are represented by electric current with respect to rated current
Multiple, the longitudinal axis represents breaker time, unit s), under the conditions of electric current is 0.09A~0.16A, during circuit breaker trip
Between about 0.02s~0.09s.If two breakers are acted simultaneously, now immediate current is combined into 0.18A~0.32A, and moment is maximum
Power is 14W~44W.
The accident indicator of the present invention has advantages below：
First, accident indicator of the invention can realize that failure sorted is indicated.According to the grade of failure, make corresponding
Different responses is indicated, is used beneficial to maintenance.Level fault is significant trouble, directly affects equipment safety, causes system can not
Normal work, or system are still run but are unsatisfactory for whole Security Function Requirements；Secondary failure is minor failure, and influence indirectly is set
Standby safety, system is still normally run, and certain influence is only caused on non-safety function.
Secondly, accident indicator of the invention uses breaker type indicating fault.Its faults state directly perceived, with biography
The acousto-optic class of system indicates that alarm is different, can remain in that fault indicating condition in the case of device power supply (DPS) closing.Breaker is ejected,
Then represent that equipment is once faulty to occur, it is necessary to artificial investigation.This mode advantageously reduces potential safety hazard.In addition, when equipment fortune
When row is normal, the detailed device Run Log without checking, it is possible to decrease the maintenance time of equipment.
It is pointed out that the present invention can provide multiple fault level classifications, and it is not limited to drawing failure shown in Fig. 1
It is divided into two ranks.For example, in one embodiment, fault level can be divided into three-level, now, indicating fault of the invention
The FPGA of device has the output of three tunnels, exports respectively to corresponding relay, breaker.Therefore, the present invention can be according to failure
The need for species, the number of breaker is freely increased or decreased.
In another embodiment, replaceable different material during breaker of the invention and resistance etc..For example, in the past
State the breaker (internal resistance is 376 Ω, and rated current is 0.05A) selected in embodiment to be defined, resistance R1, R2 there can be different choosings
Select.The breaker internal resistance is 376 Ω, according to operation curve, in order to ensure also to be operating normally under 77V, by 1.5 times of rated current
(0.075A) is calculated, and actuation time can be controlled in 0.1s, and therefore, resistance R1 or R2 resistance are not above 77V/0.075-
376=650 Ω, on the other hand, under ceiling voltage 137V, moment general power is limited by 50W, therefore total resistance in loop can not
Less than 137*137/50=376 ohm, i.e., single resistance cannot be below 376*2-376=376 Ω.Therefore the resistance R1 or R2 chosen
Standard resistance range is the Ω of 376 Ω~650.
Breaker of the rated current in the range of 0.02A-1A, resistance can be with combination replacement in the Ω of 0 Ω~1167 resistance.
In addition, the breaker loop-external power supply of the present invention can be replaced power module, as shown in Figure 3.Fig. 3 shows basis
The general principle figure of the accident indicator of another embodiment of the present invention, wherein, breaker loop-external power supply is power supply mould
Block 301,302.
